Early Detection of Breast Cancer Using Tomosynthesis Imaging

This study has been completed.
Information provided by (Responsible Party):
Duke University Identifier:
First received: March 12, 2008
Last updated: April 11, 2017
Last verified: July 2014
The purpose is to develop digital tomosynthesis to improve the detection of breast cancers. The aims are optimizing digital mammography and tomosynthesis acquisition, creating visualization tools, prospective pilot studies to evaluate radiologist performance, and computer-aided detection.

Condition Intervention
Breast Neoplasms
Radiation: Mammography and tomosynthesis imaging

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: No masking

Primary Outcome Measures:
  • Radiologist ROC (receiver operating characteristic) area under curve (AUC) [ Time Frame: at imaging review by the end of the study, approximately 9 years ]

Enrollment: 385
Study Start Date: November 2004
Study Completion Date: October 2013
Primary Completion Date: September 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Tomosynthesis scans
This is a case-only study with only one group/cohort. All women receive both mammography and tomosynthesis imaging.
Radiation: Mammography and tomosynthesis imaging
All subjects receive the same radiation dose associated with mammography and tomosynthesis imaging (which is comparable to mammography).
Other Names:
  • Digital breast tomosynthesis (DBT)
  • Breast tomosynthesis
  • full field digital mammography (FFDM)
  • screen-film mammography
  • film-screen mammography

Detailed Description:
Finding breast cancer early has been shown to improve the chance of survival. Mammography (x-ray imaging of the breast) helps find breast cancer early. Some breast cancers, however, are not seen on mammography, which creates two-dimensional images for the radiologist to see. The goal of this study is to make a breast tomosynthesis or tomosynthesis 3D (three-dimensional) x-ray system by taking x-ray images from many angles. This is similar to a CAT (computerized axial tomography) scan for the breast and can give radiologists 3D information so that they can find breast cancers which might otherwise be hidden from view.
